Urgent Help Needed (to downgrade to 1.1.4)

I am tired of 2.0's crashes, bugs and everything else it has to offer... Just want to go back to 1.1.4. I have a 1st Gen iPhone unlocked (pwnd) with 2.0. How do I go back to 1.1.4 unlocked? The tutorial in the sticky assumes that the upgrade to 2.0 has rendered my iphone locked and suggests me to wait for pwnage 2.0. So no help from there.
